CR2 vs JPG: Canon RAW vs JPEG for Photos
Published on April 2, 2026
CR2 is Canon's proprietary RAW format that stores unprocessed sensor data with 14-bit color depth. JPG is a compressed format that discards data to shrink file size. A CR2 file gives you maximum editing flexibility but takes 25-30 MB per shot. A JPG from the same camera is 5-10 MB and looks great straight out of camera but falls apart quickly if you push exposure or color corrections in post.
Image Quality and Dynamic Range
CR2 files capture 12-14 bits per channel versus 8 bits for JPG. That means CR2 holds 4,000-16,000 tonal values per channel compared to 256 for JPG. In practical terms, you can recover 2-3 stops of underexposed shadows in a CR2 without visible noise. Try the same with a JPG and you get banding, color shifts, and ugly artifacts. Highlights work the same way: overexposed areas that look pure white in a JPG often have recoverable detail in the CR2.
File Size and Storage
A Canon EOS R5 produces CR2 files around 45 MB each. The same shot as a high-quality JPG is about 12 MB. Shooting a 500-image wedding in RAW requires 22 GB of card space compared to 6 GB for JPG. Storage is cheap, but buffer speed matters too. Your camera writes JPGs faster than CR2 files, so continuous burst shooting lasts longer in JPG mode before the buffer fills up.
Editing Flexibility
White balance in a CR2 can be changed after the fact with zero quality loss. In a JPG, the white balance is baked in. Adjusting it in Lightroom or Photoshop introduces color artifacts because you are working with already-processed data. The same applies to exposure compensation, noise reduction, lens correction, and chromatic aberration removal. All of these work dramatically better on CR2 files because the original sensor data is preserved.
Workflow and Speed
JPG files are ready to use immediately. Share them, upload them, print them. CR2 files need processing in Lightroom, Capture One, or Canon's Digital Photo Professional before they are usable. If you shoot events where clients expect same-day delivery, JPG saves significant time. For commercial work where every image gets individually edited, CR2 is mandatory.
When to Shoot Each
Shoot CR2 for paid work, tricky lighting, and anything you plan to edit extensively. Shoot JPG for casual snapshots, rapid sharing, and situations where you nail the exposure in camera. Many Canon cameras support RAW+JPG mode, giving you both files simultaneously at the cost of double the storage.
